Most recent realtek drivers have a non-free firmware as byte arrays in the C files. The files have GPL license headers; but the corresponding source code is apparently not available.

for example:
  • hal/rtl8812a/hal8812a_fw.c
(from sources: aircrack-ng / rtl8812au / rtl8812au-aircrack-ng / rtl8812au-ng)

Someone would need to liberate/replace those firmwares. The architecture of the CPU of these WiFi cihp is 8051; so it's already possible to de-compile the code with radare2, and we know the entry point.
